WASHING- MACHINE.

Llliiiliit Application le July 21,

efiicient and satisfactory ltor use wherever found applicable.

One of the objects of my invention is to provide a washing machinehaving a drum of a special shape which may be operated to describe arocking movement similar to that of a rocking chair rolling back andforth on a horizontal plane or base. This action tends to give a uniformand efficientv movement of the Water or other liquid Within the'tub soas to effectively wash the garments placed therein, necessitating aminimum amount of driving mechanism or power. The load is practicallybalanced due to the shape of the drum so that there is a tendency toautomatically restore the load to equilibrium when the driving powerceases.

Another object of my invention is to provide pockets or chambers atopposite ends of the drum, said pockets being so formed that a pressureis produced therein at one direction of movement of the drum, therebyforcing air and water through the garments, and upon the oppositedirection of. movement of the drum, a suction is formed thereat, drawingair and water from the pocket through the garments.

Another object of my invention is to provide deiector or bafile means onthe drum at the bottom thereof which will cause the garments beingwashed to be turned or changed constantly, thus causing all portions ofthe load to come in contact with the liquid and the pockets, said meansalso producing a spiral movement oi" the liquid within the drum.

Many'other objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from' thedisclosure herein given.

To this end my invention consists in the novel construction, arrangementand com- Specificati'on of Letters Patent. Pamejmtd Jun@ 3139 192251921. Serial No. 466,433.

In the drawings, wherein like reference characters indicate like orcorresponding parts,

Fig. l is a side elevation of my device;

Fig. 2 is a rear end elevation thereof;

Flg. 3 1s 'a vertical section through the drum;

Fig. 4: is a section taken substantially on the line4-4 of Fig. l;

Fig. 5 is a section taken substantially on the line 5-5 of Fig. 6;

F1 6 is a section taken substantially on the line 6 6 of Fig. 5, and

Fig. 7 is a section taken substantially on the line 7 7 ofv Fig. l.

In the drawings, wherein I have illustrated the preferred embodiment ofmy invention, l `indicates the supporting frame of a machine having adriving mechanism near its bottom enclosed by a housing 2 and upon whichis detachably mounted a drum or operating tub 3. The tub or drum 3 iscon- Aends thereof are pins or rollers 5, said pins or rollers beingadapted to freely enga e in slotted openings 6 provided in the brac ets7 arranged at the opposite sides of the supporting frame' l, saidbrackets 7 having a track portion extending substantially in ahorizontal plane so as to form a horizontal or Hat bearing plate uponwhich the curved bottom of the tub is adapted to slide or rock. lfdesired, a strip of asbestos or other suitable material 8 is positionedbetween the tub and the bracket so as to eliminate noise therebetween.

Pivotally attached to one end of the tub 3 is a pitman or connecting rod9, said pitinan being preferably longitudinaliy yieldable and comprisingtwo telescopic portions 10 and 11 with a resilient spring 12therebetween, as shown in Figure 7. The tower end of said pitman isconnected to a crank 13 driven in any suitable manner, as by an electricmotor or the like., positioned Within the housing $3. il. cover plate 14of a suitable size is arranged on the upper surface of the drum for theinsertion and removal of the material to be acted upon. Arranged atoppositeends of the drum, as shown more clearly in lligures 3 and 4l areone or more varies 15, said vanes being curved so as to formsubstantially curved, tapered pockets 16 opening toward the bottom ofthe drum. The free edges of said vanes are belovv the center of the tuband preferably about half Way up from the bottom thereof. 0n the insideofthe tub is arranged a baille or deilecting rib or projection 17extending from side to side along the bottoni thereof, obliquely ordiagonally in a direction thereacross, said rib decreasingly taperingfrom its midpoint to both its ends and to opposite sides of its base sothat a transverse cross-section through said rib would be shapedsubstantially triangular', as shown in Figure 3.

'llhe rotation of the crank 13 Will operate the pitman 9 to causethedrum to rock or tilt on the horizontally extending bearing portionsor tracks of the brackets 7 the pins 5 being free in the slots' andserving merely to limit and guide the tub in its rocking movement. Thetelescopic action of the pitman parts and the free insertion and removalof the pins-5 into the slots 6 permits the tub to be readily lifted fromthe frame Whenever it is desired to do so, as for instance for thepurpose of cleaning, repairing, shipping, etc.

ln operation, assuming that the tub 3 has Water or other suitable liquidtherein and is loaded to the proper height, the rocking movementthereof. Will cause the liquid therein to follow a path somewhat asindicated diagrammatically in dotted lines in Figures y3 and a, the bodyof Water splitting at the free ends of the Vanes, asshown, a portion ofit following the outer surface of the vanes and forming substantially -afigure 8, While the other portion of the Water tends to move into thepockets 116 thereby causin the air in the pockets to be compressed by te Water. The movement of the llastmentioned Water is substantially asshown in Figure 4l; that is, it moves in a curved path in a continuousdirection Without reversal along the sides and ends of the drum; rilhisis caused by the diagonal rib 17 slopin from the center towards bothends Where y a larger proportion of the Water at the ends of the drum isto one side of the lonV itudina'l center line of the drum, and as t eseareas of majority Water supply are diagonally arranged, the direction ofthe How of the Water will be governed accordingly and will be in a.curved path about the ends andsides of the drum in a continuousdirection .as shown. The material is plunged against the pockets towardI*which'liquiid i having, so that a rinfresco cupping action isproduced, whereby the liquid will be forced through the material at thepockets and into the pockets to corn- A in air pressure therein, so thatthe air and liquidfrom the pocket is drawn or. sucked through the load.'rlfhe creating of an air pressure and a partial vacuum orsuction in theopposed pockets 16 alternates upon each rocking movement of the tub. Theoscillating motion of the tub as it rocks to and fro plunges the loadagainst the ends of the vanes where the pockets are arranged, holdingthem there While the air and liquid is driven therethrough, This actionmay be called .a cupping action because the material .is held over thepocket while the liquid and au' is forced therethrough into the pocket.

lf desired, handles 18 are arranged at opposite ends of the tub, wherebythe tub may be lifted from the frame, or, if desired, the tub may bemanually rocked. A drain 19 may be arranged adjacent the bottom of thetub, as shown. 1n case it is desired to vheat the Water in the tub afterit has been ecient and sanitary churn, or for any kind of extracting ormixing purposes, inasmuch as the smooth interior of the drum may beeasily cleaned, and my description and claims have in mind such a use. p

Having thus described my invention, 1t is obvious that variousimmaterial modiiica tions may be made in the same Without' de partinfrom the spirit of my `invention; hence l do not Wish to be understoodas limiting myself to the exact form arrangement,

construction and combination of parts herein shown and described, oruses mentioned.
